Anti-IgA Monoclonal Antibody (Clone:AD3)

Immunoglobulin A (IgA) is the major immunoglobulin class in body secretions that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract. Its serum concentration is approximately 0.2 g/l and biological survival (T1/2 in plasma) 6 days. Plasma IgA is predominantly monomeric (160 kDa) and of the IgA1 subclass, and is mostly produced in the bone marrow. Over half of IgA produced by the intestinal lamina propria plasmocytes is in oligomeric form and 35% of it is IgA2. Protein function: May play a role in the integrity of hemidesmosome and the attachment of basal keratinocytes to the underlying basement membrane. [The UniProt Consortium]
